Zooming graphs

The graph can be zoomed in and out. There are several ways of zooming the graph:

- Use Ctrl-Wheel. The current mouse position will be the zoom center
point (i.e. this point will not move during the zoom operation)
- Use the predefined 'Zoom 100%' and 'Fit window' commands. They are
available from the right-click menu or by their shortcuts: '1' and
'W' respectively. The current mouse position is the zoom center
point for the 'zoom 100%' command.
- Use Ctrl-KeypadPlus or Ctrl-KeypadMinus keys. The current keyboard
cursor is the zoom center for these commands.

There are two options linked to the graph zooming:

- Auto fit graph to window: will fit the current graph to the window
size. Default: off
- Fit window max zoom level 100%: the 'fit window' command does not
use zoom levels higher than 100%. Default: on

The zoom level is never greater than 1000% and less than 1%.
IDA remembers the current zoom level for each location in the navigation
history.
